^^ True Christopher. They are knew, but neither has broken out in my opinion either. And agreed there has been chances.
I find it hard to comprehend how there can be any valid definition by which Summer Glau hasn't "broken out." She got third billing on her second series, second billing on her third. Regardless of her billing, she was a breakout performer in terms of buzz and attention on
Firefly/Serenity and TSCC. Her image was the main one used for promotion of both
Serenity and TSCC. Her appearances in
The 4400 and
Dollhouse generated buzz well beyond their proportionate size. She's an audience and Internet favorite.
You seem to be arguing that an actor's career doesn't really count unless they achieve official star billing. That doesn't make sense. Many acclaimed actors have gone their entire careers as perennial supporting players rather than lead players. Just by numbers alone, that's the way it has to be. And you don't have to be the nominal star of a show to be its most prominent or beloved character. William Shatner was the official star of
Star Trek, but Leonard Nimoy got many times as much fan mail and was without question the most famous and iconic cast member of the show. Ron Howard was the nominal star of
Happy Days for most of its run, but he was quickly overshadowed by Henry Winkler despite the official billing. Guy Williams was the official star of
Lost in Space, but for most of the series' run, he was a background player in the adventures of Dr. Smith, Will, and the Robot.
Are these gals the only genre hotties in recent years, or are their others? IT seems there always has to be a hottie, doesn't there?
I'm sure there are plenty. That Megan Fox person gets a ton of hype, though I don't see the appeal myself. And there are others like Angelina Jolie, Natalie Portman, Scarlett Johanssen, Rhona Mitra, etc. If you're speaking specifically of television, there are a number of other beautiful actresses much admired by genre audiences and much in demand, such as Morena Baccarin, Tricia Helfer, and Grace Park. Kristin Kreuk and Kristen Bell were pretty big in TV a few years back and have now moved into movies. Amy Acker has a lot of admirers. Natalie Morales turned heads in
The Middleman and has a strong following, and I'm sure the stunning Erica Cerra of
Eureka has one too, though neither has really "broken out" yet.
And usually that part doesn't give the actress room to show their due, either.
I haven't found that to be true. Summer Glau's characters have hardly been unchallenging or shallow; they've mostly been very distinctive characters that were very challenging for an actor. And Moon Bloodgood's character on
Journeyman was definitely substantial. The same could be said for the roles essayed by most of the TV actresses I listed. I think we're well past the time when TV producers or audiences are satisfied with sexy female characters being
just sexy and nothing more.
